About Behr Sea Of Tranquility
Sea Of Tranquility is very light — LRV 82, close to white. It opens up small or dim rooms and keeps walls feeling airy. Its teal undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. In north light it can read slightly cooler; a warm white trim alongside keeps it from going clinical.
Sea Of Tranquility shines on ceilings, trim and in small or low-light rooms where you need to stretch the light — and as a calm whole-home backdrop. Greens bridge indoors and out, so they suit living rooms, kitchens and sunrooms.
